Reef Octopus Calcium Reactor CR-140 for Aquariums

The Reef Octopus Calcium Reactor CR-140 is a reliable solution for automatically maintaining calcium, alkalinity, and trace elements in demanding reef aquarium systems, typically rated for aquariums up to 150-210 gallons. It is available in both "Classic" and "VarioS" models, with the latter featuring an adjustable DC pump for enhanced control. The Reef Octopus Calcium Reactor CR-140 offers robust features and significant benefits for managing water chemistry in demanding reef aquariums. 

Key Features:

• Reverse Flow & CO2 Recirculation: A smart design feature that maximizes the contact time between the water, CO2, and the media, leading to more efficient dissolution and lower CO2 consumption.
• Solid Construction: Built with high-quality, heavy-duty cast acrylic, ensuring durability and a long lifespan.
• Built-in Bubble Counter: Allows precise monitoring of the CO2 drip rate, which is crucial for fine-tuning the reactor's performance.
• Integrated pH Probe Holder: Provides a convenient port for a pH probe (sold separately) to monitor and control the internal pH level, essential for safe and automated operation.
• Easy-to-Remove Lid: Designed for simple maintenance and easy refilling of the calcium carbonate media.
• VarioS DC Pump (VarioS model only): Features a variable speed, controllable DC pump that is energy-efficient, quiet, and "Apex Ready" for integration with aquarium controllers. 

Benefits:

• Automated & Consistent Dosing: The primary benefit is the automated and continuous supply of calcium, alkalinity, and trace elements, eliminating the need for daily manual dosing and providing rock-solid stability of water parameters.
• Long-Term Cost Effectiveness: While the initial equipment cost is higher, the ongoing expenses for media (crushed coral or aragonite) and CO2 refills are significantly lower than consistently purchasing two-part liquid supplements for large or high-demand systems.
• Comprehensive Supplementation: The process dissolves nearly all the minerals and trace elements that corals use to grow, essentially creating an "all-in-one" dosing solution that closely mimics natural reef water chemistry.
• Stable pH Levels: By maintaining consistent calcium and alkalinity levels, the reactor helps stabilize the overall aquarium pH, creating a healthier and less stressful environment for marine life.
• Reduced Maintenance: Once "dialed in," the system requires minimal maintenance, mainly just periodic refilling of the media and occasional cleaning.
• No Salinity Increase: Unlike some dosing methods that use salt-based solutions, calcium reactors do not contribute to elevated salinity, which means less frequent water changes may be needed to manage total dissolved solids
